I bought this to store my Apple MacBook Pro charger (brick and thin main USB-C cable), USB-C dongle and Apple wireless mouse . Doesn't fit all three. You can push a mouse in there, but it doesn't have velcro. Key and charger barely fit. I won't be returning it because I only get a $2 refund, but I need to use it for another purpose as I have to carry all three pieces back and forth all day. Just wanted to help with the size in case anyone else is in the same predicament.
